Our dangerous reliance on big data: in an episode recorded before the election, Rich and Paul talk to Cathy O’Neil, author ofWeapons of Math Destruction: How Big Data Increases Inequality and Threatens Democracy. They discuss Cathy’s origins in the math world, her years at a hedge fund on the brink of the 2008 financial crisis, the lack of transparency in the Department of Education’s data, and the various examples of “weapons of math destruction” in her book—all the ways that data is used to harm.
